I use Magic Eraser only on my Lyra Clavis DC, I have been strongly advised
not to use fluids on cantilevers and stylii.
Liquids are not THAT harmful - but I advise to use
damp "whatever" you are using - otherwise capillary action can indeed suck up the fluid trough the hollow cantilever,
messing up with the suspension of the cartridge, either/and/or rubber or tension wire. Cement with which diamond is usually glued to the cantilever can get compromised if fluid is allowed to act for prolonged time too - if you work damp and below 30 seconds/cleaning, liquids are safe.
I have described the
Glassrubber before; it is available under various names, here one on ebay :

It is
THE stylus cleaner, no competition for real cleaning. But I do recommend using it under the microscope to allow for application only where really needed - after thorough cleaning with Glassrubber ( heavily dirty/clogged or removal of excess mounting agents in new styli ) , Magic Eraser, Zero Dust, electronic stylus cleaner, etc is enough to keep the stylus clean during normal operation.
I only would like to warn you regarding cleaning with Glassrubber too vigorously with
shank mounted styli . That nondescript shroud covering the junction between diamond stylus itself and metal shank, which in turn is mounted to the cantilever, may well be indeed necessary to hold the diamond from falling out/off the shank.
Try to clean the diamond stylus part, particularly the record contact surface - and try to keep the shroud mentioned well alone. Should not create problems with properly mounted styli, but better to stay on the safe side. So precise work can not be done without working under the microscope.
